Add RenderView ResetDeviceColorProfileForTesting

Add RenderView ResetDeviceColorProfileForTesting

Provide a method to reset the device color profile for tests, and
make TestRunner call it prior to each layout test.

This to reset the Page color profile to its default state, to let
Page choose the default color profile, rather than TestRunner.
